Start-up expansion with funding from IFB Hamburg
The high-tech Spin-Off TXproducts, founded in April 2021 on the DESY campus in Hamburg, will receive funding from Investitions- und Förderbank Hamburg (ifb). TX stands for "Tailored X-Ray", and the company develops solutions for customizing synchrotron X-rays beams for experiments at large-scale ...
Fraunhofer IWM presents the »Triboepitaxy« concept
Four scientists from Freiburg have succeeded for the first time to simulate the localized growth of silicon crystals using shear-induced amorphization and recrystallization. In the future, experts could use this concept to tailor crystalline silicon structures for nanotechnology applications, ...
Researchers discover novel sensors
Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures. A research group led by Prof. Dr. Markus Retsch at the University of Bayreuth has produced colloidal crystals mimicking such ...
The new approach is poised to play a role in helping chemical manufacturers move away from harmful solvent catalysts in favor of water
Chemical engineers at the University of Illinois Urbana-Champaign now understand how water molecules assemble and change shape in some settings, revealing a new strategy to speed up chemical reactions critical to industry and environmental sustainability. The new approach is poised to play a role ...
The result surprised even the research group
The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating ...
New mega-crystals exhibit unique properties such as superfluorescence and may well usher in a new era in materials science
An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano "Lego bricks" interact with each other with forces vastly different and much weaker than those ...
Ionization energy is one of the most important physicochemical parameters. It is defined in terms of the amount of energy required to rip an electron from an atom. The dependence of the ionization energy on the atomic number determines the periodic law of chemical elements, which is assumed to be ...
Periodic pattern consisting of magnons is formed at room temperature
A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope MAXYMUS at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic ...
Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien. In certain materials, electrical and mechanical effects are closely linked: for ...
How crystal defects in Ni-based alloys give rise to high thermoelectric conversion efficiencies, advancing thermoelectric technology
If we are to prevent the impending environmental crisis, it is imperative that we find efficient and sustainable ways to avoid being wasteful. One area with much room for improvement is the recycling of waste heat from industrial processes and technological devices into electricity. ...
